Metrological characterization of a NaI(Tl) well counter for activity estimation prior to in vitro 131I dosimetry measurements for Nuclear Medicine patients in Nicaragua, period 2022-2023.
type: item
description: This research arose as a need to guarantee the quality of health to the Nicaraguan population according to the Plan to combat poverty and human development for 2022-2026. This research was focused on the dosimetry of nuclear medicine patients nationwide treated with 131I. The objective was to metrologically characterize a NaI(Tl) well counter to measure the activity in the patient’s blood to estimate doses in bone marrow or other organs. An iodine sample that was measured in a HPGe counter was used as a standard to achieve traceability to international standards. The study was cross-sectional in nature and focused on finding the correlation between the input stimulus (gamma radiation) and the output response of the well counter, measured in count rate kCPS (CPS, Counts per Second). Additionally, the response to the geometry of the sample, its energy and concentration was studied. The sensitivity obtained was 36.67% of the standard value measured in kBq. This result implies that, using the test method of this research, for each iodine sample subjected to counting (kCPS), when divided by the sensitivity, the activity value in kBq is obtained, with an estimated (combined) uncertainty of less than 10% of the measured activity value. This is based on the fact that for calibration, the uncertainty of the standard is 5%, which is metrologically acceptable for traceability. In summary, the findings indicate that the well counter used in this research has the necessary accuracy for its use in determining activities for dose calculations in bone marrow or other organs of interest through free access software.

Birds at the Rubén Darío University Campus of the Autonomous University of Nicaragua, Managua (UNAN-Managua).
type: item
description: Urban development and population growth generate changes in the natural environment, highlighting the importance of universities as ideal locations for studying biodiversity. However, little is known about the flora and fauna of the Ruben Dario University Campus of the National Autonomous University of Nicaragua, Managua. This study represents one of the pioneering efforts to learn about the avifaunal diversity on campus and addressing existing knowledge gaps regarding biodiversity in the municipality. This research has a mixed cross-sectional approach, employing intensive searches of individuals across three predetermined sites. We identified 98 species, of which 66.10% are resident birds, 29.34% are migratory birds and 4.56% have mixed populations (between resident and migratory). Notably, this study also records the first documented occurrences of P. holochlorus rubritorquis, Dryocopus lineatus, and Setophaga virens within the municipality of Managua. It was identified that 26.5% birds reported are identified facing varying degrees of threat. In conclusion, our findings underscore the importance of campus green spaces in supporting both resident and migratory bird populations, highlighting their potential as wildlife refuges, particularly when considering the broader surrounding environment.

Didactic strategy Illustrations as a contribution to the understanding of the topic value chains in the industrial engineering major of the UNAN-FAREM-Carazo
type: item
description: A study was conducted at the Universidad Nacional Autónoma de Nicaragua, Facultad Regional Multidisciplinaria de Carazo, to evaluate illustrations as a didactic strategy for reading comprehension of written documents provided by teachers during classes given at the UNAN-Managua, FAREM-Carazo, this is a descriptive, transversal, The information was contrasted with the main theories on reading comprehension and didactic strategies, to make a correct triangulation of the information collected, revealing that there is no general procedure or methodology used by teachers in its application. Likewise, during the execution of the subject "value chains" in the first year of the industrial engineering course in 2018, an opinion test and an evaluation rubric were applied to the students, which allowed an analysis of the different data collected, making use of frequency quantification utilizing bar graphs. When analyzing the importance of the illustrations strategy in the value chain topic, it was determined that students have a good level of acceptance of the illustrations in written documents and there is an improvement in their reading comprehension when they are used as a didactic strategy since they allow greater accessibility of the contents, increase the retention capacity of the concepts and there is an improvement in their synthesis capacity.

Education in the field: contextualization of student permanence in the primary and secondary education modality.
type: item
description: Distance education in the countryside is an action strategy implemented by the current government in the basic and middle education subsystems, in which the entire community of the country’s public schools participate to strengthen scientific and practical knowledge that promotes social development in rural communities. In this article, the indicator of permanence of students in the modality of primary and secondary distance education was analyzed taking as a reference the enrollment of the years 2021 and 2022, through a methodical process of scientific character. The rural population in 2019 represented 41.24% in the country. The enrollment of primary distance education in the countryside during 2021 compared to 2022 was 2,662 to 2,344 with a difference of 318 students, the discrepancy reflects a reduction as a positive indicator, due to the fact that students transcend from primary to secondary education in the countryside, which demonstrates the educational commitment of the students, most of the primary enrollment in the countryside is concentrated in the Autonomous Regions of the North and South Caribbean Coast and Jinotega. Secondary enrollment in the countryside has presented a variation from 2021 compared to 2022, going from 60,474 in 2021 to 60,938 in 2022, increasing by 464 students, this figure is due to the continuity of students coming from the primary education modality. Secondary school enrollment in the countryside has presented a variation in 2021 compared to 2022, going from 60,474 in 2021 to 60,938 in 2022, increasing by 464 students, this figure is due to the continuity of students coming from the primary school modality, the enrollment is concentrated mainly in the departments of Matagalpa, the Autonomous Regions of the North and South Caribbean Coast and Jinotega, the permanence indicator shows that the expectations of positive results in education in the countryside have been achieved.

Generic competencies and their effect on the professional training of university students
type: item
description: The purpose of this article is to determine the level of generic competence (technological and creative) and the effect it has on the professional training of university students. This is a descriptive study with a quantitative approach. A questionnaire was used as a technique and a survey of open and closed questions as an instrument. For the application, the Microsoft Forms 365 tool was used and the link was shared with the informants via WhatsApp. The sample consisted of 37 students enrolled in the Elective component Tools for the Creation of Digital Educational Materials (HCMED) at UNAN, Managua. As part of the main findings, it is highlighted that students achieved significant competence in the use of web tools, the creation of digital materials, the ability to be creative in the design of digital resources, the search for digital information in reliable sites and respect for copyright, seen from the professional ethics. However, it is evident that one of the competencies that needs to be strengthened is the contextualization of information reflected in academic and didactic documents. In addition, it is concluded that the generic competencies (technological and creative) are essential in the student’s professional training to obtain learning results in accordance with the professional profile and, therefore, with the needs of society.

Moodle virtual platform as a support tool in secondary education
type: item
description: In this work, a proposal was made for the implementation of a virtual learning platform as a support tool in secondary education. A non-experimental cross-sectional design with a qualitative approach was applied. The instruments used were interviews containing open-ended questions on the state of technological resources and digital competencies of teachers. An analysis was made to know the current situation of the Colegio Sagrado Corazón de Jesús Bethlemitas and to identify the technical requirements and technological competencies of teachers necessary for the implementation of the Moodle virtual platform. As a result, the school, although it has a computer lab, does not have computer resources for the installation and management of the Moodle platform. In addition, the office automation requirements necessary for the implementation of the Moodle virtual platform, human and technological resources are indicated. From the results obtained, it is concluded that for the implementation of the Moodle virtual platform, the infrastructure of technological equipment and a designated staff for the updating and configuration of the computer service of the virtual platform must be guaranteed. In addition to a designated staff for teacher counseling.

VENN diagrams extended to event complements for solving conditional probability and Bayes' theorem.
type: item
description: All roads lead to Rome, goes an old saying. In the world of mathematics, a given problem has many ways of being solved, some of which can be complex and others very simple and straightforward. It is important to note that the person trying to understand or learn mathematics needs the quickest way of understanding. Venn diagrams have been widely used in the solution of probabilities including the conditional and Bayes’ Theorem. However, we can use this technique to extend the complements of the events that are dealt with in each problem to optimize calculations and thus be able to answer all the probability questions that the problem relates to. Within the technique is to form the interlocking circles indicating the common region for each of the events to be treated and thus their respective complements. As there are 2 events, 4 areas will be formed that have been named as petals, which are equivalent to the difference or sums with the total probability of each event as the case may be.

Meckel's diverticulum in Nicaraguan adults. Report of two cases and review of the literature
type: item
description: Introduction: The cases described discuss the prevalence of this clinical entity simulating an acute surgical abdomen in adult men and compares the approach to symptomatic and asymptomatic Meckel’s diverticulum. Methods: This case report was reported using the international guidelines that guide the aspects of writing and publishing a surgical case report, mentioned in the SCARE guide (Surgical CAse REport, 2020). Case presentation: Male patients aged 31 (case 1) and 19 years (case 2) respectively, who attended the unit with acute surgical abdomen in whom Meckel’s diverticulum was diagnosed incidentally (case 1) concomitant with acute and symptomatic appendicitis. (Case 2) complicated by inflammation, a location was observed on the antimesenteric side of the ileum, approximately 80 cm from the ileocecal valve, with a length that ranged from 2 (case 1) to 10 mm (case 2). Diverticulectomy was performed, using the wedge reception technique with primary anastomosis (case 1) and intestinal reception with approximately a 5cm margin of the diverticulum with end-to-end anastomosis in two planes (case 2), the approach was successful in both patients. Conclusion: The diagnosis of complicated Meckel’s diverticulum in adults is difficult because the clinical characteristics in patients with complications are non-specific and are not clinically distinguishable from appendicitis. Exploratory laparotomy seems to be an ideal surgical approach in cases of acute surgical abdomen. with uncertain diagnosis.

Complex perspectives in education: Beyond dichotomies
type: item
description: The purpose of this academic essay is to reflect on the need to transcend the dualities that modern rationalization imposes on us. In education, this is obvious, because it limits the realities of education, which go beyond models and methods, which are inadequate. However, these have something good, therefore, it is necessary to look at a new educational epistemology that allows observing in a trans complex way the educational realities of cultures and their intentions. An archaeoepistemology that can observe reproductions, continuities, and ruptures in time and space, as well as what societies and people want, overcomes the impostures of centers of power. Therefore, it is important to decolonize knowledge and streamline models that in most cases include the past and present, but also focus on the future.

Chronic kidney disease associated with heat stress: a literatura review
type: item
description: The purpose of this scientific literature review document is to demonstrate the incidence of Chronic Kidney Disease in field workers caused by thermal stress. The Prisma methodology was applied to documents published in databases such as Google academic, Scielo, Bireme, Lilacs in which publications were found that address the topic of thermal stress in the labor sector; The publications consulted were from 2018 to 2023. It is necessary to emphasize that chronic kidney disease has increased in work sectors with exposure to high temperatures and that it mainly occurs in the countryside and production areas. (Ruiz Herrera, 2020). Global warming is causing an increase in exposure to high temperatures in confined environments, internal environments in production areas and also in open environments, which is why it directly affects the health of workers. (ILO, 2023). As a result of the review, 15 articles on occupational safety and heat stress were included. Among the conclusions of this review, it was found that the workers studied are characterized by being exposed to high temperatures without wearing clothing appropriate to the work environment or that protects them from exposure to ultraviolet rays and therefore experience an increase in body heat, added to This means they have long working hours, do not take breaks and do not ingest adequate fluids recommended by an occupational doctor or the person in charge of occupational hygiene and safety; The incidence of kidney disease associated with heat stress was 41.9% in males with an age of presentation of 46 years, in stage II, with work-related heat stress as the main risk factor.

description: Ethidium bromide (EtBr) is a fluorescent dye widely used for staining nucleic acids in agarose and polyacrylamide gels. However, EtBr has several drawbacks, such as its high toxicity and mutagenic capacity, which restricts its use and management. In this study, the use of GelRed®, an alternative dye developed by Biotium, which offers greater sensitivity, safety and stability than EtBr, was evaluated. The performance of both dyes was compared for the staining of DNA amplified by PCR, using the protocols of BCR-ABL, JACK2, ESBL, carbapenemases IMP, VIM, SPM, GIM, NDM, KPC, OXA, mcr-1/mcr-2 and mecca. The results indicated that GelRed® can be used to visualize DNA with a fluorescence intensity equal to or greater than that of EtBr, without the need to modify the extraction, amplification and electrophoresis protocols. Furthermore, GelRed® did not interfere with restriction enzymes and PCR, and does not exhibit mutagenic or cytotoxic effects. It is concluded that GelRed® is a safe and sensitive option compared to EtBr for staining nucleic acids in agarose gels.

The STEAM Methodology and PBL in the Integration of Knowledge and Development of Mathematics Competencies
type: item
description: The development of mathematical competencies in high school students is currently a challenge. To overcome it, teachers implement various methodologies and strategies aimed at making the knowledge of this discipline more accessible. In this regard, the present research analyzes the effectiveness of the STEAM methodology (Science, Technology, Engineering, Arts, Mathematics) and Project-Based Learning (PBL) in the development of mathematical competencies in eleventh-grade high school students. The main objective was to evaluate how the STEAM and PBL methodologies promote mathematics learning and the development of skills such as critical thinking, creativity, and teamwork. The research followed a non-experimental design, with a mixed-methods approach, mostly quantitative, at a descriptive, cross-sectional level. A survey was conducted with a sample of 17 eleventh-grade students from the Santa Teresa National Institute, along with interviews with two Physics and Mathematics teachers. This was carried out during the second semester of 2023. The results reveal that students positively value the integration of disciplines and the practical application of mathematics, showing significant improvements in their understanding of mathematical concepts. Additionally, collaboration in STEAM and PBL projects strengthened teamwork skills, although a need for greater variety in practical projects was identified.

Rol del profesorado para responder a las necesidades de la universidad actual
type: item
description: En el presente artículo se hace una reflexión desde una perspectiva analítica e interpretativa de la autora, sobre las necesidades del profesor universitario, en términos de competencias en el nuevo contexto de la cibersociedad y la sociedad del conocimiento según las nuevas demandas de la universidad. Se aborda la evolución de la profesión docente y las nuevas necesidades surgidas a partir del cambio de contexto externo e interno. Se hace una revisión bibliográfica sobre las nuevas exigencias, rol y funciones del profesorado, y la influencia de los diferentes modelos educativos asumidos a lo largo de su evolución. Se identifican las características que deben tener los docentes llegando a la conclusión que ya no es suficiente dominar un área específica del conocimiento, ni el solo hecho de poseer títulos de especialidades, maestrías y doctorados para lograr ser un docente de calidad. La realidad a la cual se enfrentan los profesores en la actualidad demanda de ellos un rol integrador entre la amplia variedad de alumnos que se les puede presentar, en el que el docente es un agente educador y socializador, asumiendo incluso responsabilidades fuera de sus clases, resultando evidente que ya no basta poseer competencias de orden escolar, sino que la sociedad demanda también competencias relacionales y emocionales.

Los comerciantes informales de Nicaragua todavía tienen cajonería de oro, medias de seda, sombrero de castor... , “…y los príncipes venden tinajas en los mercados…”, Ernesto Cardenal
type: item
description: Este estudio tiene como objetivo revelar las contradicciones histórico-sociales del comercio informal en Nicaragua, desde la perspectiva de la tradición literaria nicaragüense, de la que da cuenta El Güegüence. En lo metodológico, corresponde a una investigación cualitativa y se utilizó el método inductivo, se hizo un análisis y comparación de la información documental con los resultados encontrados en el trabajo de campo, lo que develó que los desplazados o marginados siguen encontrando en el comercio informal una válvula de escape para sobrevivir, cuestión que refuerza la presencia del mito mercurial encarnado en el Güegüence, en contraste con el papel histórico de la administración pública interesada únicamente en la recaudación de impuesto. Finalmente, se recomienda para futuras investigaciones contar con que la realidad es contradictoria y generadora de contradicciones.
